Answer 1

Favourite answer

 Let x be the number of people on the train.

 x - 19 + 17 = 63

 x = 65

 There were 65 people on the train.

Answer 2

63-17+19 = 65 <<<

To check: 65-19 = 46

46 + 17 = 63

Answer 3

At start, x were on the train. Then 19 got of leaving x-19 on the train. Then 17

got on, leaving x-2 = 63 on the train. So x = 65.

Answer 4

If 19 people got off but then 17 people got on, that's the same as if only 2 people got off.

Add back the 2 people and you have 65 that were on the train to begin with.

Answer:

65
